METALLIC RAILWAY TIE.

APPLICATION FILED 00120, 1914 Elimina@ l it, fi, respectively, butl this construction is optional and forms no essential part of my present invention. f

A. leading feature of the present invention is in forming the pressed steel. sections of the tie in such manner thatthe sections cooperate to 'form vertical spike receiving openinvs, e', located at opposite sides of and vertical receiving openings being closed on all sides except the top and bottom, and the vertical iianges of thesections being slightlyiiared transversely, as at 13, to enable the spike receiving' openings to be satisfactorily formed in and between the relatively thin edgewise standing flanges, b, of the tie, a portion of each of said spike receiving openings being pressed in each of the sections and the matching portions of the spike receiving openings cooperating to form a complete box. Each Vof the spike receiving openings also comprises two opposite walls, o2,

Fig. li,- which are sinuous or made with alf tornate' curved projections and depressions, ra transverse ortion of each of these walls 'being forme. ineach of the pressedsteel sections, before mentioned.VY y

Each A of; the spike-receiving openings f forms a'vertical spike-receiving recess of serpentine form into whichthe ordinary and substantially straight railway spike, f', is designed to be -driven and tobe distorted durin the operation, as shown in F i 4, where y the spike is made to substantially conform tothe wavy outline of the walls, c, c2, of the opening against which the spike is forced as it is driven into place.

The sinuous walls ofthe opening, therefore, give a corresponding wavy form to the spike which greatly adds to the security vwith which the'spike is held. These walls also have-the function of again straightening the spike when the saine is withdrawn.

4When it isfdesired to adjust the rails transverselyv to take up or compensate `for wear of the treadsof the rails I employV suitablel metal shims, D, which may be normally straight, and which are placed in the against' one of the sinuous wallsj openin t ereo whereby upon driving the spike in place the shim is crowded against and into vthe curvatures of the wall, and is thereby so distorted as to make it conform sub-v stantially to the wavy surfaces thereof, as shown in"l1`ig.f 4=; at the same time the spike which is, confinedy between the shim` and the opposite sinuous wall of the opening is distorted. anfli'inade ,toconform substantially f to'thefor'nration thereof and also to that of; thefdistorted'shim. The pressed steel sections may also be forniedxalong their upper outer sides with a strengthening rib,

11i, which extends substantial y from end to end of thejsections, .as shownin Fig. 1. The describedgtie is light and yet strong;

y below .each rail-seat, said spike vit is comparatively inexpensive, and it ywill be found an excellent substitute for the ordinarywooden tie, as also for the metal and composite tie now used for similar purposes. f

Having thus described my invention what l claim as new and desire to secure by Letters Patent is s 1'. A metallic railway-tie formed of similar sections of pressed metal each having a vertical fiange extending longitudinally n thereof and being formed integrally with a part of a rail seat and a part of an interior spike-receiving opening, said sections coperating to form complete seats, and so said openings being disposed at opposite sides of each of said seatsrvand each of said openings extending toward the base of the tie, and having opposed interior walls of sinuous form adapted to distort normally substantiallyA straight spikes when the latter are 4forcibly driven vinto the opening when in engagement with said Walls.

2. A. metallic railway-tie formed of similar sections of pressed metal each fashioned with a .horizontal fiangeV and a flange at. right-angles thereto and extending longitudinally along the same, and means for uniting the sections of the tie, said sections having `their upper edges near the' ends, 95 formed with transverse oppositely projecting matching flanges which constitute 'widened rail seats, said vertical flanges of the sections being formed on4 their inner surfaces at opposite sides of each rail seat 109 with matching portions of a spike-receiving opening, each of said openings having opposed sinuous walls adapted to distort a spike simultaneously With ,the driving of the same into an opening whereby the spike is made' to confor-1:? substantially to the wavy outline of said walls.

3. A metallic railway-tie formed of similar sections of pressed metal each having a vertical flange and having matched portions 110 at the ,topconstituting a rail-seat, each section of the tie having matching ortions in their inner surfaces adapted to orm spikereceiving openings, said openings being vertically-disposed at opposite sides of each of the rail-seats and having opposed sinuous inner walls, a portion of cach of which is formed in each of the pressed sections of the tie, said,sinuous walls adapted toy distort a spike forcibly driven into said open- 12 ings whereby the spike is made to substantially conform to said walls. y

4. A metallic railway-tie formedof 'similar sections of pressed metal each having a v ertlcal flange and lhaving matching `portions at the top constituting a rail-seat, each section of the-.tie havin matching portions i in their inner surfaces a apted to yform spikereceiving openings, said openings being. vertically-dlsposed at opposite sides of the raill" 1,127,3ao g 4seats sind. having opposed sinuous inner walls, a portion of each of which is formed in each of the pressed sections of the tie,

l said sinuous Walls adapted to distort a spike le by and in unison with the distortion of the spike.l v

5. A- railway-tie formed of similar sections of pressed metal each having a ange standing on edge and the inner surface of 1li each Harige near the ends being formed with parts of a pair of spike receiving recesses, parts of each of said recesses matching to form a.V complete opening and certain of the Walls in the corresponding inner surfaces of the anges bein sinuous and adapted to distort a. spike riven orcibl into the opening in contact with sid slnuous Walls.

In testimon whereof I aix my signature in presence o two witnesses.
